The crockmeters are used for friction colour precision testing perfomed by fricting the textile materials to another accompanying fabric, with the method of colour change at the sample and staining of the accompanying fabric.
The samples are fricted to the dry, un-dyed and cotton accompanying fabric. The staining ratio of the accompanying fabric is determined upon the staining gray scale.
The device has an electronical controller and an engine. |
